When it is needed to fix the valve core 20 relative to the valve seat 10, the locking pin 30 is rotated to the first position, at this time, the locking pin 30 can move axially relative to the sliding groove 11, one end thereof can move towards the valve core 20 and can be clamped in the locking hole 21, when it is needed to lock the opening position and the closing position of the valve core 20, the opening locking hole and the closing locking hole can be arranged on the valve core 20 and are distributed along the circumference of the valve core 20, when the valve core 20 is rotated to the opening locking hole corresponding to the locking pin 30, one end of the locking pin 30 can be clamped in the opening locking hole, thereby making the flow channel 13 in the opening state, when the valve core 20 is rotated to the closing locking hole corresponding to the locking pin 30, one end of the locking pin 30 can be clamped in the closing locking hole, thereby making the flow channel 13 in the closing state; when it is needed to unlock the valve core 20, the locking pin 30 can be moved to the direction away from the valve core 20 and be rotated to the second position and clamped in the sliding groove 11 to limit the movement of the locking pin 30 to the direction of the valve core 20, at this time, the locking effect of the locking pin 30 and the valve core 20 can be released, then the valve core 20 can rotate relative to the valve seat 10, in this process, the user does not need to exert force on the locking pin 30 all the time, therefore, the labor intensity can be reduced, the assembly efficiency of the connector can be improved and the use convenience can be improved.

[0029] In some embodiments, the side wall of the sliding groove 11 is provided with a first limiting groove 12 in communication with the sliding groove 11, wherein the extending direction of the sliding groove 11 is parallel to the axial direction of the valve seat 10, and the extending direction of the first limiting groove 12 can be perpendicular to the extending direction of the sliding groove 11, for example, the first limiting groove 12 and the sliding groove 11 can form a T-shaped groove or an L-shaped groove, wherein the horizontal structure of the T-shaped groove refers to the sliding groove 11, and the vertical structure refers to the first limiting groove 12; the vertical structure of the L-shaped groove refers to the sliding groove 11, and the horizontal structure refers to the first limiting groove 12; in addition, the first limiting groove 12 can also be inclined towards the direction of the valve core 20. The side wall of the locking pin 30 is provided with a lever 31, and the lever 31 protrudes from the sliding groove 11, wherein the lever 31 can be perpendicular to the locking pin 30, and the position of the lever 31 on the locking pin 30 can be close to one end of the locking pin 30 towards the valve core 20, or can be located at the middle of the locking pin 30, or can be located at one end of the locking pin 30 away from the valve core 20. When the locking pin 30 moves away from the valve core 20 to make the lever 31 move to correspond to the first limiting groove 12, it can be rotated into the first limiting groove 12, thereby realizing the clamping of the lever 31 in the first limiting groove 12, so as to limit the axial movement of the locking pin 30. The cross section of the lever 31 can be circular or rectangular, etc., wherein when the cross section of the lever 31 is rectangular, the contact area of the side surface of the lever 31 with the first limiting groove 12 can be increased, thereby ensuring the stability of the lever 31 clamped in the first limiting groove 12; when the cross section of the lever 31 is circular, an arc-shaped groove can be arranged on the side wall of the first limiting groove 12, and when the lever 31 is rotated into the first limiting groove 12, the arc-shaped side surface of the lever 31 can be in surface contact with the arc-shaped groove, thereby ensuring the stability of the lever 31 in the first limiting groove 12, so as to prevent the lever 31 from moving out of the first limiting groove 12 when rotating the two valve seats 10. In addition to the above-mentioned way to improve the stability of the lever 31 in the first limiting groove 12, the lever 31 can also be adsorbed in the first limiting groove 12 by magnetic attraction, for example, a magnet can be arranged on the lever 31, a magnetic material is arranged in the first limiting groove 12, or a magnet is arranged in the first limiting groove 12, a magnetic material is arranged on the lever 31, or a magnet is arranged on the lever 31 and the first limiting groove 12 respectively, which can be adsorbed in the first limiting groove 12 after the lever 31 is rotated into the first limiting groove 12. In addition, the first limiting groove 12 can also be designed as a tapered structure, such as a dovetail groove, or when the cross section of the lever 31 is circular, the first limiting groove 12 can be designed as an arc-shaped groove with an opening slightly larger than or equal to the diameter of the lever, and the lever 31 can be rotated into the first limiting groove 12 from the tapered portion, and due to the limiting effect of the tapered portion, the stability of the lever 31 clamped in the first limiting groove 12 can be effectively improved.It should be noted that the above embodiments only list some ways to ensure the stability of the dial lever 31 in the first limiting groove 12, in addition to which other structures can also be used to improve the stability of the dial lever 31 in the first limiting groove 12.

[0030] The first position refers to the position of the locking pin 30 turned out of the first limiting groove 12, and the second position refers to the position of the dial lever 31 turned into the first limiting groove 12. It should be noted that the slot width of the sliding groove 11 should be smaller than the diameter of the locking pin 30 to prevent the locking pin 30 from being pulled out of the sliding groove 11, and the slot length of the sliding groove 11 defines the movement range of the dial lever 31, and the first limiting groove 12 can be arranged on the side wall of the sliding groove 11 away from the valve core 20.

[0031] In some embodiments, the side wall of the sliding groove 11 is further provided with a second limiting groove in communication with the sliding groove 11, and the first limiting groove 12 and the second limiting groove are distributed along the extension direction of the slot length of the sliding groove 11, wherein the second limiting groove can be parallel to the first limiting groove 12, and the first limiting groove 12 and the second limiting groove can be arranged on opposite side walls of the sliding groove 11 or on the same side wall, for example, the sliding groove 11, the first limiting groove 12 and the second limiting groove form an F-shaped groove, wherein the vertical structure of the F-shaped groove refers to the sliding groove 11, the upper horizontal structure refers to the first limiting groove 12, and the middle horizontal structure refers to the second limiting groove. When one end of the locking pin 30 is clamped in the locking hole 21, the dial lever 31 can be turned to the second limiting groove, so as to clamp the dial lever 31 in the second limiting groove, thereby limiting the axial movement of the locking pin 30, thereby improving the position accuracy of the locking pin 30 and the valve core 20 when locked. It should be noted that the cooperation relationship between the dial lever 31 and the second limiting groove can be set by using the cooperation relationship between the dial lever 31 and the first limiting groove 12 to improve the stability of the dial lever 31 in the second limiting groove.

[0032] In some embodiments, the end of the locking pin 30 away from the valve core 20 abuts against the sliding groove 11 by the elastic member 40, which can be a spring. The spring is arranged in the sliding groove 11, and the end of the sliding groove 11 away from the valve core 20 is closed. One end of the spring can abut against the closed end. When the locking pin 30 rotates to the first position, the locking pin 30 is clamped in the locking hole 21 under the elastic force of the elastic member 40. When the locking pin 30 rotates to the second position, the elastic member 40 is compressed. For example, when the lever 31 on the locking pin 30 rotates into the first limiting groove 12, the spring can abut against the lever 31 in the first limiting groove 12. When the lever 31 rotates out of the first limiting groove 12, the spring can push the locking pin 30 to move towards the valve core 20. As to the connection mode of the spring, one end of the spring can be fixedly connected with the locking pin 30, and the other end can abut against the end of the sliding groove 11 away from the valve core 20. Alternatively, one end of the spring can be connected with the end of the sliding groove 11 away from the valve core 20, and the other end can abut against the locking pin 30. Alternatively, both ends of the spring can be connected with the sliding groove 11 and the locking pin 30, respectively. Alternatively, both ends of the spring can abut against the sliding groove 11 and the locking pin 30, respectively. In addition, in order to facilitate the adjustment of the extension amount of the spring, the end of the sliding groove 11 away from the valve core 20 is in communication with the outside of the valve seat 10. The end of the sliding groove 11 away from the valve core 20 is provided with a threaded hole. An adjusting screw can be threadedly connected with the threaded hole from the rear end of the valve seat 10. Both ends of the spring can abut against the locking pin 30 and the adjusting screw, respectively. When the adjusting screw is screwed, the elastic force of the spring can be adjusted.

[0033] In some embodiments, the opening of the end of the locking hole 21 towards the locking pin 30 is flared. The side of the first limiting groove 12 away from the valve core 20 is provided with a guide slope 121. When the locking pin 30 is in the state that the lever 31 is clamped in the first limiting groove 12, the end of the locking pin 30 towards the valve core 20 is located in the flared opening. When the valve core 20 is rotated, the flared opening of the locking hole 21 pushes the locking pin 30 to move away from the valve core 20. Under the action of the guide slope 121, the locking pin 30 rotates during the movement away from the valve core 20, so that the lever 31 is withdrawn from the first limiting groove 12. At this time, the locking pin 30 abuts against the valve core 20 under the elastic force of the elastic member 40. For example, when the locking pin 30 is in the extended state and clamped in the opening locking hole, if it is needed to rotate the valve core 20 to the closed state, the end of the locking pin 30 clamped in the locking hole 21 is first moved to the flared opening of the opening locking hole, and the lever 31 is clamped in the first limiting groove 12. Then, the valve core 20 is rotated, so that the flared opening pushes the locking pin 30 to continue to move away from the valve core 20. Under the action of the guide slope 121, the locking pin 30 rotates, so that the lever 31 is withdrawn from the first limiting groove 12. When the valve core 20 is rotated to the closed locking hole corresponding to the locking pin 30, the locking pin 30 is pushed into the closed locking hole under the elastic force of the elastic member 40.

[0034] In some embodiments, as shown in FIG. 1 and FIG. 2, the valve seat 10 comprises a valve body 14 and a valve cover 15 connected to the valve body 14 to form a cavity accommodating the valve core 20. For example, a cylindrical segment 141 coaxial with the valve body 14 can be arranged at one end of the valve body 14 towards the valve cover 15, and the outer diameter of the cylindrical segment 141 is smaller than that of the valve body 14. The valve cover 15 can be fitted on the cylindrical segment 141 of the valve body 14, and then fixed on the cylindrical segment 141 of the valve body 14 by fasteners. Specifically, a plurality of fixing holes can be arranged in the circumferential direction of the valve cover 15 and the cylindrical segment 141, and the fasteners can be inserted into the fixing holes. In order to ensure the accuracy of the installation position of the valve cover 15 and the valve body 14, a plurality of positioning grooves 142 distributed in the circumferential direction can be arranged on the outer periphery of the cylindrical segment 141, and the groove length extension direction of each positioning groove 142 is parallel to the axis of the cylindrical segment 141. The inner side of the corresponding valve cover 15 is provided with a positioning protrusion matched with the positioning groove 142. The positioning protrusion and the positioning groove 142 can prevent the valve cover 15 and the valve body 14 from rotating relative to each other. The stepped surface between the cylindrical segment 141 and the valve body 14 can serve as an axial limiting surface for the valve cover 15, thereby improving the assembly accuracy of the valve cover 15 and the valve body 14. The outer periphery of the valve body 14 is provided with a first groove 111, and the slot opening at one end of the first groove 111 faces the valve core 20. The side wall of one end of the valve cover 15 facing the valve body 14 is provided with a second groove 112. The first groove 111 and the second groove 112 form a sliding groove 11. The sliding groove 11 is designed in two parts, which can make full use of the structure on the valve cover 15, and thus can be effectively applied to scenarios where the axial length of the valve seat 10 is short. In addition, the sliding groove 11 can be integrally arranged on the valve cover 15 or the valve body 14 to reduce the manufacturing difficulty.

[0035] In some embodiments, the push rod 31 extending from one end of the sliding groove 11 is provided with a pushing part 32, which can be in the form of a plate or a block, for example, a pushing plate can be arranged at the outer end of the push rod 31, and the pushing plate is preferably parallel to the locking pin 30. In order to facilitate the user to operate the pushing plate, anti-slip structures such as patterns or other concave-convex structures can be arranged on the outer surface of the pushing plate. In addition, for the block-shaped pushing block, in order to facilitate operation, a block structure with a V-shaped groove can be selected, which facilitates the user to push the locking pin 30 forward and backward.

[0036] In some embodiments, the pushing part 32, the pushing rod 31 and the locking pin 30 are integrally formed, for example, by injection molding or other processes, which can improve the convenience of assembly. In addition, in order to reduce the wear of the locking pin 30 on the valve core 20, the head of the locking pin 30 can be designed as a spherical end, and the opening of the locking hole 21 at the end of the locking pin 30 can also be designed as a flared end to improve the smoothness of the locking pin 30 in the locking hole 21.

[0037] In some embodiments, the side wall of the locking pin 30 is provided with an axial direction extending guide groove and a circumferential direction extending limiting groove, the guide groove and the limiting groove are communicated, and the side wall of the sliding groove 11 is provided with a limiting block. When the valve core 20 needs to be rotated, the locking pin 30 can be first pushed away from the valve core 20 to move, so that the limiting groove corresponds to the limiting block, and then the locking pin 30 is rotated around the second axis 301 to make the end of the limiting block extend into the limiting groove, so as to achieve the purpose of limiting the axial movement of the locking pin 30. At this time, the locking pin 30 is withdrawn from the locking hole 21, so that the valve core 20 can be rotated relative to the valve seat 10. When the valve core 20 is rotated to the position of opening the flow channel 13 or closing the flow channel 13, the locking pin 30 is operated to rotate so that the limiting block corresponds to the guide groove, and then the locking pin 30 is moved towards the valve core 20, so that one end of the locking pin 30 is clamped in the locking hole 21, that is, the relative position of the valve core 20 and the valve seat 10 is fixed.

[0038] It should be noted that, in addition to the pushing rod 31 provided on the side of the locking pin 30, the user can also directly operate the locking pin 30 from the slot of the sliding groove 11, and the operation part can be provided on the end of the locking pin 30 away from the valve core 20, which extends from the valve seat 10 along the axial direction of the locking pin 30. The user can move and rotate the locking pin 30 through the operation part. The limiting part can be provided on the inner wall of the sliding groove 11 away from the valve core 20, which can block the locking pin 30 from moving out of the sliding groove 11. For example, the locking pin 30 is a stepped shaft structure, and the sliding groove 11 is a stepped groove structure. The rear section with a smaller outer diameter of the locking pin 30 can extend out of the rear section of the sliding groove 11, and the user can operate the rear section of the locking pin 30 to move or rotate the locking pin 30. The front section with a larger outer diameter of the locking pin 30 is located in the front section of the sliding groove 11, and the locking pin 30 and the sliding groove 11 can limit the locking pin 30 from moving out of the rear end of the sliding groove 11 through the stepped surface.
